    2. Complex differential variance angiography with noise-bias correction for optical coherence tomography of the retina

      Complex differential variance angiography with noise-bias correction for optical coherence tomography of the retina
      Complex differential variance (CDV) provides phase-sensitive angiographic imaging for optical coherence tomography (OCT) with immunity to phase-instabilities of the imaging system and small-scale axial bulk motion. However, like all angiographic methods, measurement noise can result in erroneous indications of blood flow that confuse the interpretation of angiographic images. In this paper, a modified CDV algorithm that corrects for this noise-bias is presented. This is achieved by normalizing the CDV signal ...

    3. Repeatability and reproducibility of automatic segmentation of retinal layers in healthy subjects using Spectralis optical coherence tomography

      Repeatability and reproducibility of automatic segmentation of retinal layers in healthy subjects using Spectralis optical coherence tomography
      Purpose: To evaluate the repeatability and reproducibility of automatic segmentation in healthy subjects using a Spectralis optical coherence tomography (OCT) system. Methods: A total of 60 eyes from 60 patients were included in this prospective study. Spectral-domain optical coherence tomography images were generated using the Spectralis OCT system. An automated algorithm was used to segment the macular retina into nine layers and evaluate the thickness of each layer in the ...

    8. Thickness mapping of individual retinal layers and sectors by Spectralis SD-OCT in Autosomal Dominant Optic Atrophy

      Thickness mapping of individual retinal layers and sectors by Spectralis SD-OCT in Autosomal Dominant Optic Atrophy
      Purpose To assess layer- and location-specific retinal thickness deficits in autosomal dominant optic atrophy (ADOA) using Spectralis SD-OCT. Methods This cross-sectional study included 41 ADOA patients with OPA1 exon 28 (2826delT) mutation [age, 8.683.5 years; best-corrected visual acuity (BCVA), 889 Early Treatment Diabetic Retinopathy Study (ETDRS) letters] and 55 mutation-free first-degree relatives as healthy controls (age, 8.968.7; BCVA, 8099). Participants underwent routine examination and optical coherence ...

  2. About Heidelberg Engineering

    Heidelberg Engineering

    Heidelberg Engineering. Ophthalmology Systems. Heidelberg Engineering has paved the way for quantitative retinal imaging in glaucoma management. The Heidelberg Retina Tomograph was the first instrument of its kind available on the market for the routine glaucoma exam. It follows that Heidelberg Engineering has the longest history and the most experience and knowledge of the subject. The high quality and reproducibility of our products have been proven over time by the accuracy and consistency of glaucoma follow-up exams.
    The reason for this is that Heidelberg Engineering has ensured that there is a solid scientific base to all products.
    The company has always been involved in basic research projects, and our technical knowledge is unsurpassed. Heidelberg Engineering is an extremely innovative company. It is the integrity of research and consistency of approach that enable our products to be used with confidence in the clinical environment. Our track record of product development is exceptional! Look at the development milestones achieved during the past 10 years.

  3. Quotes about Heidelberg Engineering

    1. I am becoming a big fan of spectral-domain OCT, especially Spectralis [Heidelberg Engineering, Vista, Calif.]...To this point with time-domain OCT, I have not been convinced that you can use this technology to follow patients over time. Now, with the faster image acquisition and better axial resolution we see with SD OCT, there is better quantitative peripapillary retinal nerve fiber layer measurement for glaucoma management. The improved accuracy of the OCT segmentation allows for better long-term evaluation of patients.
